摘　　要：数字电位计是一种由数字输入控制的可调电阻,它既有基本的可变电阻特性,又具有温度补偿、写保护、非易失性等特性,因此在增益控制、电源控制等方面得到广泛的应用。介绍了AD公司生产的数字电位计AD5235的特点,将其应用于应力信号的调理电路中,实现了应力信号调理的数字化,提高了调理精度和效率。DigitaI potentiometer is a variabIe resistor controI ed by a digitaI input,not onIy it have the basic characteristics of a variabIe resistance,but aIso has other properties,such as temperature,write protect,non-voIatiIe,etc.Therefore it is wideIy used in gain controI,power controI and so on.This paper introduces the feature of AD5235 and appIies it in stress signaI condi-tioning circuitry.It has achieved the digitization of stress signaI conditioning and improved the accuracy and efficiency.
